Release of perfluoroalkyl substances from AFFF-impacted concrete in a Firefighting Training Ground (FTG) under repeated rainfall simulations
Science
7 Feb 2022 | J. Hazard. Mater.
High concentrations of 5 PFAS were measured in concrete cores removed from firefighting training grounds, and simulated rainfall released approximately 1% of the total PFAS mass in the concrete surface layer, leading researchers to believe that concrete can be a secondary source of PFAS contamination.
